I that that that now and then come up with is like a question for you done three or four heads in a row you might think it's going to ... affect what will happen on the flip flip ... flip is completely independent having nothing to do that ... Penney doesn't know ... what is the Performance flips in the same way ... the stock market more or less is looking forward it doesn't look pass ... eventually moving the point that is that ... there been so a few years ... the ... first half like this one ... already I it's worth remembering that the long-term average return for the entire year ... is around ten or eleven percent while the Dow was up by thirteen point eight percent ... for the first six months the US or were already ahead ... of what we would normally I would normally was expect for a full year or so ... there are many who think well it's not a knee in a state money on which it that ... we should check out our blessings and be done with it but it turns out that ... that really has nothing to do with what the market will likely give the next six months that they ... are doing well only are no different ... regardless of what happened for six months the ... high mark over that stuff as always
